Eaton CH280 - 80 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

Meet the Eaton CH280 — a purpose-built 80A, 240V, 2-pole plug-in molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Engineered for fast installations and precise protection, this CH-series breaker excels in residential, commercial, and light industrial settings where reliability matters.

• Fast plug-in connection: streamlined, tool-free installation that snaps into compatible panelboards, reducing downtime during both new builds and panel upgrades.
• Thermal-magnetic trip unit: delivers stable, repeatable protection by combining instantaneous magnetic tripping for short circuits with thermal protection to minimize nuisance trips during moderate overloads.
• OEM-compatible design: engineered to align with matching Eaton load centers and panelboards, ensuring a clean fit, consistent performance, and straightforward replacement when needed.
• Versatile 2-pole protection: ideal for safeguarding 240V branch circuits and feeders, including key residential and light commercial loads, while providing reliable short-circuit interruption when necessary.

Tips for installation and maintenance

• Follow local electrical codes and the manufacturer’s installation instructions to ensure safe, compliant operation.
• Use the correct panelboard model and confirm that the CH280 is the proper plug-in fit for your Eaton load center.
• Before servicing, power down the main disconnect and verify absence of voltage in the work area; replace only with the specified amperage and pole configuration.
• Periodically inspect the breaker and panel for signs of wear, corrosion, or overheating, and replace if you notice abnormal warmth or tripping behavior.
